Here's where my past posts intersect.
How do you know what needs doing when you discover that by some miracle you have no homework due tomorrow?
That big calendar on the wall where you have been adding all the due dates for assignments, projects and research papers, along with tests and every possible deadline or scheduled anything.
It's how you know that even with two weeks to work on a project, you only have this Sunday afternoon to work on it. You can see how jammed up you are just by looking.
If you're smart, you've been scheduling in the fun stuff too, just to make sure it doesn't get lost in all the work.
Then, if you're lucky, one day you will look at the calendar and see that you really do have nothing to do today but hang out.
It could happen.
